Hybrid tomato variety ‘H1991’

ABSTRACT

Hybrid tomato variety ‘H1991’ is described. The tomato variety is a ground-culture hybrid processing tomato variety suitable for machine harvest and is adaptable to the arid climactic conditions of regions such as California, USA, Spain, and Portugal. It is a main season variety with resistance to the three known races of fusarium wilt plus tomato spotted wilt virus. Its thick juice viscosity and medium solids makes it suitable for concentration and its smooth fruit shape lends itself to whole peel applications.

FIELD

This disclosure relates to the field of plant breeding. In particular,this disclosure relates to a new variety of tomato, Solanum lycopersicumvariety denominated ‘H1991’.

BACKGROUND

Breeding improved tomato varieties involves providing genetics that givean advantage to the grower, processor, consumer, or other members of thesupply chain. The improvement may be in the form of field performance,disease resistance, factory performance, or a fruit qualitycharacteristic. For a tomato variety to be suitable to be grown forprocessing, the variety must have a concentrated fruit setting andmaturity, firm fruit, and sufficient rot tolerance to allow early fruitto remain rot-free while later fruit continues to develop and ripen.

Most tomato varieties for commercial processing are hybrids resultingfrom a cross pollination of two true-breeding, inbred parents. Throughthe use of true-breeding lines, a hybrid is produced that often displayscharacteristics of each parent, and often demonstrates characteristicsthat are superior to either parent alone, or that allow a hybrid to maskinadequacies of the individual parents.

Processing tomato varieties combining resistance to verticillium wiltrace 1 (Verticillium dahlia), fusarium wilt races 1 and 2 (Fusariumoxysporum pv lycopersici), bacterial speck race 0 (Pseudomonas syringaepv. tomato), and root knot nematode (Meloidogyne incognita) are highlydesirable in most climates around the world. Moreover, in regions suchas California, the industry has seen a considerable increase in pressurefrom tomato spotted wilt virus (TSWV) and fusarium wilt race 3. Thus,varieties with both resistances are in very high demand by both growersand processors to ensure a productive crop cycle and desirable factoryperformance.

Processing tomato quality parameters differ from those of fruit used inthe fresh market. The processing characteristics are typicallydetermined using a sample of hot-break tomato pulp or juice produced ina consistent manner to those familiar with the art. For example, a fixedmass of tomatoes may be cooked in a microwave oven for several minutesto halt any enzymatic breakdown of the sample, lost water is replaced,and the sample is pulped to remove skins and seed to produce a uniformjuice sample. The juice sample can be analyzed for various qualityparameters important to processing tomato including but not limited togross viscosity measures such as juice Bostwick, soluble solids measuresusing a refractometer (°Brix), measures of acidity and pH, and measuresof color (e.g., a Hunter a/b score). The value of these traits dependson the product that is being commercially produced by the processingfactory. In some instances, a factory will put a higher value on a thickviscosity variety, whereas in other instances, a thin viscosity willmake a superior product and is preferred.

DETAILED DESCRIPTION

Described herein is the new and distinct tomato variety named ‘H1991’that was developed to provide a ground-culture hybrid tomato variety(i.e., not grown on stakes) that is suitable for machine harvest, andare adaptable to the climactic conditions of regions such as California,USA, Portugal, and Spain.

Processing tomato varieties combining resistance to verticillium wiltrace 1 (Verticillium dahlia), fusarium wilt race 1 and 2 (Fusariumoxysporum pv. lycopersici), bacterial speck, root knot nematode(Meloidogyne incognita) are highly desirable in most climates around theworld. Varieties with resistance to fusarium wilt race 3 and tomatospotted wilt virus are highly desirable in California as the incidenceof these diseases throughout the state continues to increase.

Tomato plants of ‘H1991’ are resistant to verticillium wilt race 1,three known races of fusarium wilt, root knot nematode, bacterial speckrace 0, and tomato spotted wilt virus. Plants are dark green in colorwith an upright, somewhat open habit that can lead to some of theexposed fruit becoming slightly sunburned as compared to tomatovarieties of the same market class. Mature fruit of ‘H1991’ areextremely firm, very smooth, and medium in size (68 grams). Bothinternal and external color are strong.

Stability of Variety ‘H1991’

The variety is uniform and stable within commercially acceptable limits.As is true with other tomato varieties, a small percentage of variantscan occur within commercially acceptable limits for almost anycharacteristic during the course of repeated multiplication. However, novariants were observed during the three years in which the variety wasobserved to be uniform and stable.

Data in Table 1 is based primarily upon trials conducted inCollegeville, Calif. from two replications, non-staked, in a researchplot environment. Data in Tables 3 and 4 are based upon observationsmade in trials throughout California and Ontario, Canada. Comparisonsamong varieties for processing traits (Table 2) were done over two yearsof side-by side testing throughout California. Disease resistance andadaptability assessments are based upon DNA markers associated with thedisease resistance when available or numerous observations collected inregions/climates with specific disease pressure, specifically for ripefruit rots, bacterial spot, bacterial canker, early blight, and lateblight, including Ontario, Canada.

Both ‘H1991’ and ‘H5608’ have similar crop maturities, in the mid-seasonclass, yet there are several characteristics that can distinguish‘H1991’ from the commercial variety ‘H5608’. ‘H1991’ has a blockier,fruit shape than ‘H5608’. The fruit color of ‘H1991’ is very good, and adeeper red color than ‘H5608’, particularly in its locular gel.Agronomically, the major advantage of ‘H1996’ is that it carriesresistance to Fusarium oxysporum race 3, which is lacking in ‘H5608’.Varieties with good field performance, thick (low) juice Bostwick, andwhich also carry resistance to fusarium wilt race 3 are currently highlyvalued by the processing tomato industry.

FURTHER EMBODIMENTS

Additional methods provided herein include, without limitation, chasingselfs. Chasing selfs involves identifying inbred plants among tomatoplants that have been grown from hybrid tomato seed. Once the seed isplanted, the inbred plants may be identified and selected due to theirdecreased vigor relative to the hybrid plants that grow from the hybridseed. By locating the inbred plants, isolating them from the rest of theplants, and self-pollinating them (i.e., “chasing selfs”), a breeder canobtain an inbred line that is identical to an inbred parent used toproduce the hybrid. Accordingly, another aspect of the disclosurerelates a method for producing an inbred tomato variety by: plantingseed of the tomato variety ‘H1991’; growing plants from the seed;identifying one or more inbred tomato plants; controlling pollination ina manner which preserves homozygosity of the one or more inbred plants;and harvesting resultant seed from the one or more inbred plants. Thestep of identifying the one or more inbred tomato plants may furtherinclude identifying plants with decreased vigor, i.e., plants thatappear less robust than plants of the tomato variety ‘H1991’. Tomatoplants capable of expressing substantially all of the physiological andmorphological characteristics of the parental inbred lines of tomatovariety ‘H1991’ include tomato plants obtained by chasing selfs fromseed of tomato variety ‘H1991’.

One of ordinary skill in the art will recognize that once a breeder hasobtained inbred tomato plants by chasing selfs from seed of tomatovariety ‘H1991’, the breeder can then produce new inbred plants such asby sib-pollinating, or by crossing one of the identified inbred tomatoplant with a plant of the tomato variety ‘H1991’.

The disclosure further includes introducing one or more desired traitsinto the tomato variety ‘H1991’. For example, the desired trait mayinclude male sterility, male fertility, herbicide resistance, insectresistance, disease resistance, and drought resistance.

The desired trait may be found on a single gene or combination of genes.The desired trait may be a genetic locus that is a dominant or recessiveallele. The genetic locus may be a naturally occurring tomato geneintroduced into the genome of a parent of the variety by backcrossing, anatural or induced mutation, or a transgene introduced through genetictransformation techniques. For a genetic locus introduced throughtransformation, the genetic locus may comprise one or more transgenesintegrated at a single chromosomal location. Accordingly, the disclosureprovides tomato plants or parts thereof that have been transformed withone or more transgenes (i.e., a genetic locus comprising a sequenceintroduced into the genome of a tomato plant by transformation) toprovide a desired trait. In one aspect, the one or more transgenes areoperably linked to at least one regulatory element. In one aspect, thetomato plant or plant part comprising a transgene has all thephysiological and morphological characteristics of tomato variety‘H1991’.

The gene(s) may be introduced to tomato variety ‘H1991’ through avariety of well-known techniques, including for example, molecularbiological, other genetic engineering, or plant breeding techniques,such as recurrent selection, backcrossing, pedigree breeding, molecularmarker (Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), and Simple SequenceRepeats (SSRs) (also referred to as Microsatellites)), enhancedselection, genetic marker enhanced selection, and transformation.Accordingly, tomato seed, plants, and parts thereof produced by suchgenetic engineering or plant breed techniques are also part of thepresent disclosure.

Also provided herein are single locus converted plants and seedsdeveloped by backcrossing wherein essentially all of the morphologicaland physiological characteristics of an inbred are recovered in additionto the characteristics conferred by the single locus transferred intothe inbred via the backcrossing technique. A single locus may compriseone gene, or in the case of transgenic plants, one or more transgenesintegrated into the host genome at a single site (locus). One or morelocus conversion traits may be introduced into a single tomato variety.In one aspect, the tomato plant or tomato plant part comprising a singlelocus conversion has all the physiological and morphologicalcharacteristics of tomato variety ‘H1991’.
